SHP file polygons
Submitted by rkmcswain on Fri, 03/05/2010 - 07:28If you have ever imported an ESRI SHP file containing polygons using the ._MAPIMPORT command, and the polygons came in filled, you may have wondered how to turn off this fill.
Use the ._POLYDISPLAY command to enable or disable the fill on these MPOLYGON objects.
Command: ._POLYDISPLAY Enter mpolygon display mode [Edges only/Fill only/Both]: _E
If for some reason, you don't want MPOLYGON objects, you can control the default object import type (MPOLYGON vs. closed polyline) by running the MAPUSEMPOLYGON command.
Command: MAPUSEMPOLYGON Enter new value for MAPUSEMPOLYGON: _OFF
Importing SHP Polygons
Submitted by rkmcswain on Tue, 06/16/2009 - 17:01If you are importing ESRI SHP files that contain closed objects using the MAPIMPORT command, and you end up with filled MPOLYGON objects instead of plain old closed polylines, read on....
First, you can instruct MAP to import closed polylines instead of MPOLYGONs by running the MAPUSEMPOLYGON command and setting the value to OFF. If you do want MPOLYGON entities, but you don't want them filled, run the POLYDISPLAY command and choose Edges only. Be sure to REGEN after running this command.
